;. OBTURATING nnvron 2 2 Application filed June 23, 1931, SerialNo. 546,372, and.- in France July 12, 1930.

My invention has forits object a device for obturating an orifice. 'A characteristic feature of the device. according to my invention consists in providing, in the vicinity of the orifice to be obturated, a movable piece adapted to bedisplaced with respect thereto. A lid pivoted, through a point close to its periphery, eitherto-the part tobe obturated or tosaid movable piece, and preferably at a point close to the edge of the orifice, is operatively connected to said movable piece in such a manner as to beactuated by a very small displacement of the movable part with respect to the partwhi'ch is to be ob- According to another feature of my invention, a pin, integral either with one of the parts (movable part or part to beobturated) or with the lid, can be displaced in an eccentric groove either of the lid or of one of the two parts above mentioned, and causes .the lid to pivot when said parts are displaced with respect to eachother.

My invention also relates to tubes, recipients and-all objects ordevices having an orifice, or opening, provided with an obturating device according -to my invention.

Preferred embodiments of my invention willbe hereinafter described with reference to the accompanying drawings given merely by way of example and in which:

Fig. llis avertical section ofanother embodiment rof my invention. I I 7 ,In the. embodiment shown in. Figs. lto i, the box comprises aninner container 1, the outside part .of which is cylindrical, the-inside being of anyshape-whatsoever. A cylindrical casing 2 is rotatably mounted oncylinder 1 with-a snug fit. I It'is preferablethat bottom 3 of container 1, should have: adiameter larger than casing 2 and should be providedwith a-series ofnotohes, forexample, toallow oftakinggholdeasily of containerl in order to move casing2. -.-,The ca'sing may, to this efiect, comprise a series of'recesses l, whichmay be ofcircular shape. and disposed on the peripheryof saidcasin g, 5

A flat lid .5 is pivoted, at a point close to its periphery, about .an' axis 6 nfixed through any suitable means to container 1 at right. angles to said. lid. I V

-I11' l3h6 vicinity of the point about which it pivots, lid 5 comprises, on its inner, surface, a grooveor slot 7, which. is engaged-by the head of pin 8 fixedtocasing 2=by any suitable means. This groove 7 is eccentrica'lly located with respect to the center=of lid 5.

When it covers the orifice of tube or box; 1, lid 5 is held in position by an appropriatedevice. In the embodiment of Figs. 1 to 3, the

edge of lid 5 is thinned along a partof its periphery, that is along a m b, Fig. .2. When container 1 is closed, said thinned edge fits into a circular groove Qprovided in the corresponding side of casing.2, ona-level with the top ofcontainer 1: (Figs.= 1 and; Preferably,..the edge of the other part a 17. bis flanged towards container 1, so as to fit over the edge of-said container in thesame way-as an ordinary lid, and suitably cut out in the vicinityof point a so as not to-interferewith the opening movement. To this effect, the top part of casing 2 is suitably slit at point 10, along that line-of its periphery which corre sponds to part an 6 of-the lid (Fig.3).

The operation of myzdevice-isas follows: When casing 2 is rotatedwith respect to box 1 in the direction of arrow ji (Figs. 2 and 4), pin,8 rotates in thesame direction with relation to axis 6 and causes lid 5 to pivot by acting upon the edge 0 of groove 7 along the different points on which it bears successively. This displacement causes box 1 to open. In order to close said box 1, casing 2 is rotated, with relation to the box, in the direction opposite' tothat indicated by arrow 7. Pin 8 then causes lid 5 to rotate by acting upon the edge (1 of groove 7. Said lid thus pivots about its axis 6 and covers box 1. vThese dif ferent operations can be performed with one hand. a

It is quite evident that axis 6 of lid 5 could be supported byicasing 2, pin 8 being, in this.

case, integral with box 1. Again,pin 8 could be supported by lid' 5, the corresponding groove 7 being "provided in'the form of a cavity, either in cylinder 1 or in casing 2.

Another embodiment of my invention is shown in Figs. 5 to 7, where lid 5 is applied against inner box 1 so as to be integral therewith once the obturating operation is completed. To this e'flect, casing 2 is so devised as to be able to slide and pivot on box 1, by means of one or more pins 11 integral with said casing. Each of the pins 11' is movable in a groove 12 of'box 1. Said groove 12 has a part which is inclined, provoking, through the pivoting movementof casing 2, a longitudinal displacement of the latter on box 1. while asubstantially horizontal part of said groove 12 allows of a simple rotary movement of said casing 2 with relation'to box 1, when the former is in its upper position. Obviously, pins 11 might be fixed to box 1 and grooves 12 might be provided in casing 2.

Casing 2 comprises an inward flange 13 which is applied against the edge of lid 5. Preferably, lid 5 is of reduced thickness on its periphery, as shown at 14, so that edge 13 of casing 2 may be supported by the thinned part and thecentral part of lid 5 may fit into the opening limited by edge 13. Thus,when casing 2 is lowered, lid 5 is held down firmly so as to avoid any displacement which might bend said lid or the pins, thus ensuring a tight closing of the box. i

In order to insure a free passage for lid 5 when box 1 is being opened, casing 2 is provided with a lateral slot 15 (Figs .5and 7) the breadth of which is slightly wider than the thickness of lid 5 and the length of which is about equal to halfthe circumference of the casing. Preferably, a, horizontal lug 16 is provided, which is fixed on the outside, of casing 2, on the level of the lower part of slot 15, s; as to support lid 5 when it is outside cas- 111g V Groove 7 of the lid in which pin 8 moves is open on the periphery of said lid, so as to allow for the moving in and out of said pin 8. Lid 5 comprises moreover a,circular groove 17 which allows for the displacement of said pin 8 during the rotation of easing 2 that corresponds to the upward displacement of said casing. For the same reasons, box l'comprises a notch 18 in which pin 8 can freely be displaced.

Box 1, when closed, is completely covered by lid 5, which is held down by casing 2, the

moving in the inclined part of the groove or grooves 12, casing 2 is displaced axially with respect to box 1 in the direction of arrow f (Fig. 5). Meanwhile, pin 8 moves in slot 18 of box 1 and in circular notch .17 of lid 5 without actuating the latter.

, When pin, or pins, 11 reach the top of the slopes of-groove, or grooves, '12, casing 2 is sufficientlylifted to bring lateral slot 15 of said casing on a level with lid 5. From that time on, when casing 2 is pivoted, it remains on thesame level with respectto box 1, owing to the horizontal portions of slots 12. In that second part of the pivoting movement of casing 2, pin 8 engages groove 7 of lid 5 and causes said lid 5 to pivot by acting upon edge c of the groove. Lid 5 is moved out of casing 2 through slot 115, thus-uncoveringbox 1.

To close the box, casing 2 is rotated with one hand,-with respect to said box, in the direction opposite to that indicated by arrow f. The same movements as above described take place in the opposite direction,'pin 8 bearing on edge (Z ofgroove 7. I

In the two embodiments of my invention that have been above described, the box is opened through the slight pivoting movement obtained by displacing, with one hand, casing 2 with respect to box 1 in a determined direction. Itis closed by the same pivoting movement effected in the opposite direction.

The box could also be successively opened and closed through a rotary movement in one direction only, no matter which, as shown, for example, in Figs. 8, 9,10 and 11.

In the embodiment shown by Figs. 8, 9 and .10, lid 5 is fixed to a vertical axis 19, on which is keyed pinion 20. Said pinion 20 and axis 19 are disposed in a recess 21 provided in the lateral surface of box 1, said pinion 20 projecting outwardly from said surface. Pinion 20 meshes with toothed rim 22, placed inside casing 2, where it is fixed by any suitable means. Thus, the rotary displacement of easing 2 about box'1 causes pinion 20v and lid 5 to rotate successively, producing the opening and closing of box 1. Of course, pinion 20 and axis 19 on which is fixed lid 5 might also be mounted on casing 2, toothed rim 22 being then fixed to the outer lateral surface of box 1 and the teeth of said rim being on the outside.

When pinion 20 is supported by box 1, casing 2 preferably extends above the top of said box and is provided with a circular groove 23 on a level with the upper edge of said-box, theidiam'eter of said: roove? 23 being substantially; equal to that-o Jilid5, so that, .when thebox is closed-,said 1id-5fits intosaid groove 23 and is thusamaintained in position.

- In. order that the-rotary displacement; of casing'2, with respect itolbox l,.may:produce the displacement Offlid 5,-it is thereforenecessary for said casing toibeifirstlowerei with respect to thebox, into: a positionswhi'ch awill disengage said lid 5. s This isobtained automatically in the embodiments shown in Figs. 8- to "10,. through a ideviceszsimilare. to; that whichisshown in Figskto f7. s 1

:In this arrangement, pin, or pins; .11, carried bybox 1', move in a continuous groove 12 of casing 2. T Said "groove. 12 comprises horizontal 2= portions which correspond to the simple pivoting movement of casing 2:=with respect to box 1 inthe lower: portioniof the casing. Preferably, notches 251areprovided in the middle of :said horizontalportions, in order to more firmlyimaintainithe position of the casing and of all themovable parts-when at rest. "Said horizontal portions: are connected to each othersby sloping parts located below said horizontal portions,;so. that when pins 11 move in said sloping parts, due toithe pivoting movementof casing 2, said'casingis raised or lowered with respect to box 1.

i Lid-5 must be rotated only when'it is disengaged: from slot: 23,. viz, when casing2 is in its lower: position: with respect: to: box 1. This corresponds to ithel passa'ge of pinsll in the horizontal portions'of'groove 112. To

this effect, rim 22 is toothed only at'intervals,

the toothed portions beingr' separatd by smooth intervals. Said toothed portions are so disposed that pinion i 20 engages the teeth of one of saidintervals during the'passage of pins 11in the horizontal portions of groove 12 and the number of teethiof each toothed'portion is equal-to that ofpinion20.

Thus, when'box' 1 is closed,*casing 2 is in the-upper position, pins 11,"carriedby box 1',

being at the bottom of the sloping portions of groove 12 of casing'2. Lid 5: is i mobt lized in groove 23 and pinion 20 :is located between two toothed portions of rim22.

To open the box, casing 2 is pivotedwith respect to box 1 in any'direction. As pins 11 move along the sloping parts of groove-12, casing 2 is lowered andwdisengages lid=5. W'hen casing 2 is in its-lower-position and pins 11 are at the top: ofthe 'sloping. parts of groove 12, pinion 20 comes into contact with the teeth of a toothed. portion of rim 22. In that manner, when'casing2 is further rotated, lid 5 is caused to rotate and uncovers box 1. The length of each horizontal portion of groove 12 being equal :to the circumference of the pinion, lid "-5 has 'rotated through 180 WhGIl'PlIllOIl 20 reaches themiddle of the toothed portionof rim 22', pins 11 being then inthe middle of: the horizontal portions of groov 12.

'duces, as in thepreceding exa1i1ple,the

2 Whatever theldirection in which: casing 2is further rotated, rlid: 5also pivots in; the same direction about its axis and is broughtwinto .a position lIIWlIlGlIiit covers box. 1.' At that time, pinion20 leaves the toothed portion-of 1 the rimwsothat itis no=longer driven thereby.

PinslL-moverdow'n: the sloping portions of lateral outer portion of box l 'andithe teeth of said rim aredisposed ontheoutside. The toothed rim might also be; replaoed, as-:shown ini'Fig; 11,-by projections 27-suitably disposed on theouterrsurface ofxbox' l. 1 v

In the last mentioned" embodiment, 1 +5 may be provided with a circular recess-or groove26- which is engaged b y the; edge of box 1 in the closed position, so as torinsure fluid tightness. Inthatposi-tion;casing 24s in the lower positionwwith respect torbox 1.

Preferably, a piece 28, having the shape of a horseshoe, :is' fixed, through one-of its branches, to casing 2, at right angles to the plane of "lid 5' and at: a point diametrally opposits/to axis: '19, thebranches of-z'the horse shoe being radiallyfdisposedxwith respect to the casing. 1 The positioning 'ofithat piece is such that, when the boxis being. closed, the edge of lid 5 is brought between the branches of :thezhorse shoe inside which it is thusiimmobilized by the upperbranch. I a

r Inv order 'toopen'box 1, the casing is-caused t0: rotate about said? box- :until it'is. brought into the upper position. for which the circular groove26of 'llClf-il is released from the edges of "the box. F'romwthat time on,:;as pinion :20 x is in mesh with projections '27,: a slightmovement of rotation ofrcasing' 2 pro- 1voting-of lid 5', so as to=uncoverbox 'll 7 1T oclose the boincasing 2-is rotated, with respectto saidboxyin any direction whatever. Lid 5;is thus-broughtover box 1,- the: edge of said lid in the-portion oppositeito-axisfli) beingwbroughtbetwecn thebranches of piece 28;when lid 5-coversbox 1', pinion 20 leaves the toothed portionv formed by projection .27 and-casing 2 moves :ina downward direction with respect to the box and 'drivesalong-lid '5cin'i-ts motion. Groove 26 ofisaid lid is thus applied against the upperedge'ofbox l. 3 In that way, owing to'groove'26- andto piece 28, the'box is closed in fluid-tight manner.

- Itwill be readily understood that pinion -20 and'toothed rim 22 or projections 27 might be'replaced by frictional surfaces.
